Hey, if Gillette and Schick can get it, more power to them. The correct price is the price the customer is willing to pay. If they are willing to pay the price, well, good for them.
For me, I can get 100 Derby blades for about $17.00. That's two year's worth. I have no clue how long a five blade cartridge lasts. If I used one I would keep on using it until it was beyond offering a decent shave. With the Derby's I don't care.
I have often wondered if the popularity of the stubble look is in anyway related to having to shave with a multi-blade cartridge, the price of it and the suspect quality of the shave.
Of a thousand shavers, two do not shave so much alike as not to be distinguished.
